I believe Henrik has found and fixed this issue, but I don't know if it is in the beta3 version. He has been talking about a new release.

There could be something wrong with the caching. (we have it disabled). Anyone got an idea where to look further ? Dominique On 01/10/11 12:23 PM, Dominique Frise wrote:
Hi,
This is probably a duplicate of http://www.xymon.com/archive/2010/01/msg00139.html
We are running xymon-4.3.0.beta3.
The "CPU Load" and "Users and Processes" graphs of the trends column show random 10min holes (see attached holes.png). The other graphs are OK.
We see this behaviour on all Solaris and MacOSX clients; Linux and Windows clients are NOT affected. There is nothing in clientlaunch.log (client) or rrd-status.log (server)
